If an SBS
Spill Containment System
is supplied the rack will be installed inside the polypropylene spill pans. Polypropylene is acid
resistant, extremely strong and can support up to 15,000 lbs. per square inch without degradation of the material. SBS supplies
different size spill pans that are ‘butted’ together in different combinations to form different spill containment system lengths and widths.
Flexible connectors are supplied to ‘connect’ the pans together.
If the rack and spill containment need to be anchored to the floor you will follow the previous rack installation instructions; however, you
must also assemble and place the spill containment system under the rack before marking the anchor holes. After the anchor holes are
marked, drill through the pans and then drill into the floor. Insert anchor bolts and tighten.
Where needed, caulk hole/bolt with silicon to provide a 100% leak proof spill containment system.
After rack and spill containment system are installed, ensure all bolts are tight and properly torqued.
Optional electrolyte absorbing/neutralizing pillows can be placed in the spill pans after the battery installation is complete.
Installation of Cells/Batteries
B
atteries supplied in filled and charged condition are ready for direct installation. If not already done the transport seal (red plastic film)
should be removed from inside each vent cap and the transit polarity caps should also be removed and discarded.
Begin installing the batteries on the lower step or tier for stability and safety reasons. Batteries should be placed on the rack as the
intercell connectors dictate. Carefully follow the polarity sequence to avoid short circuiting cell groups.
Talcum Powder may be used on the platform surface or rails to ease movement.
DO NOT USE
any other type of lubricant such as
Grease or Oil as they may contain mineral spirits which can cause crazing and cracking of the plastic jar material.
Make sure to arrange batteries plumb and level with the correct polarity – see series vs. parallel connection for explanation.
Series Connection
– batteries are usually installed in series.
Place the batteries on the rack making sure that the positive terminal of one battery is connected to the negative terminal of
the next battery and continue in the same fashion. Make sure batteries are aligned properly.
Parallel Connection –
Batteries may be connected in parallel to give higher current capability. In the case of parallel
connected strings, use only batteries of the same capacity, design, and age, with a maximum of four parallel strings.
After cells are positioned on rack install intercell connectors and jumper cables. Use the correct torque to tighten the terminal bolts as
indicated below. After connections are torqued the connectors and terminal screws should be coated with a thin layer of anti-corrosion
grease or petroleum jelly.
Bolt Diameter
Recommended Torque
M6
66 in-lbs (7.5 Nm)
M8
177 in-lbs (20 Nm)
M10
265 in-lbs (30 Nm)
Charger Connection
Before the charger is connected, make sure the cells are clean and double check all connections for correct torque and polarity.
Ensure all connections have appropriate internal resistance values.
With the charger switched off, the battery fuse removed, and the load disconnected, connect the battery to the DC power supply.
Ensure that the polarity is correct – positive terminal of the battery to the positive terminal of the charger.
Switch on the charger (per charger instructions) and adjust the float and equalize voltages as needed.
Figure 1:
These are two 6 Volt batteries in series to
produce 12 Volts. You can add more
batteries for a higher voltage, i.e. 24, 48, 130
Vdc.
Figure 2:
These are three 12 Volt 100 Ah batteries in
parallel. They produce 12 Volts with 3X the
capacity (300 Ah) of a single battery.
